Hi, Andy from Essex, UK here, have a mariner blue Mk1 MX5 with PNP megasquirt and a hybrid Evo 6 turbo, puts out just over 260bhp

love the thing to bits, scares me to death, but has recently developed an irritating misfire when on boost/full throttle/higher rpm

I stumbled across this place and from what I’ve seen I am already very confident that you guys will be able to help!

Andy
